Using Mythological Creatures Made Common
I can’t really think of many Indian or Hindu mythological creatures that have been assimilated into the public consciousness like you say, but one thing that happens that I wish wouldn’t is the occasional use of Hindu deities as villains.
Kali and Shiva tend to get the worst of it in this regard, because they’re deities associated with destruction, and can be quite terrifying in some depictions. Kali, for example, gets portrayed as a System Lord in Stargate, and is not a nice person, to say the least. And while she never appears in Indiana Jones and the Temple of Doom, the heart-ripping bad guys are flagrantly depicted as a Kali cult.
As a philosophical skeptic who doesn’t believe in the factive reality of any gods, you might not think I would care about this, but the effect of this trope isn’t the vilification of deities but the othering of the people whose culture surrounds those deities, whether they actually believe in them or not. With Abrahamic religions and Christianity in particular being so dominant in the west, such that even most atheists in America or Europe approach their non-belief from an ex-Christian perspective, Hindu iconography, cosmology and practice falls so outside this general sphere that we’re markedly other already. Thus assimilating into Western society already comes with an immense pressure to abandon your cultural traditions, even the purely material ones, because said society contains a streak that seems so incompatible with your ancestral philosophies. So when those weird four-armed, elephant-headed, funny-colored gods show up in mainstream media as evils to be defeated, it paints the culture around them as backward and superstitious at best and barbaric at worst.
You can still do things with Hindu deities in fiction, and some works I’ve read that do are actually very good and well-written even if the premise is somewhat uncomfortable at times (Zelazny’s Lord of Light comes to mind). I mean, here, I even made a snarky post a couple of years ago about how you can assemble an entire Avengers team out of Hindu deities: http://science-of-noise.tumblr.com/post/56186438978/that-awesome-moment-when-you-realize-you-can-build
(I guess I’ll have to add guys for The Vision and Scarlet Witch now).
The thing about Hindu gods is that they can be very compelling characters. Keep in mind that Hinduism is the last living continuant of the reconstructed Indo-European religion, which spawned the Norse gods, the Greek gods, and more. Like those pantheons, the Hindu deities are super-human and extra-ordinary (note the hyphenation), and so in some Hindu stories they can be portrayed as fallible and even amoral, because their roots lie in a philosophical system that was primarily concerned with keeping the world turning, as opposed to the grace and salvation narrative of, say, Christianity. Many times, the Hindu gods do not give humans any special status above other forms of life, which can be baffling to outsiders. There are some very interesting and compelling narratives that can be built out of this, which is why seeing the deities devolved into villainy is disappointing and saddening.
We’ve got some badass demons and monsters who I haven’t seen much of in fiction at all: vetālas, bhūtas, and pishachas are quite nasty (pishachas particularly so), and they’re rarely portrayed as anything but evil and troublesome, so negative portrayals of those probably wouldn’t cause too much furor. Asuras and rakshasas are generally evildoers but on a more human scale. They are less often portrayed as outright monsters as humanoid races who have a propensity to go astray in various, often bloody ways. The issue with that is that they are involved in so many obviously Hindu stories, and are not always evil (they may be virtuous but corrupted, scholarly, and worship various gods, and some are even heroic), and they form a large part of Hindu philosophical underpinnings usually as foils for righteousness. It would be difficult and potentially offensive to use them out of context.
This is all just my personal opinion, and while I consider myself quite well-informed, I can’t speak for all Hindus. Many would be annoyed and angry at depictions that I might have suggested are okay. While I personally think those folks could stand to lighten up a notch or two, I can’t discount their opinions as invalid, so just be aware that what I have to say on the matter is likely going to err on the laissez-faire side of things.

For me, I believe some mythological creatures shouldn’t be in public consciousness. I’ve found Native beliefs in particular bastardized and appropriated left and right, especially in new age religious circles. White people have become the authority on Native spirituality in mainstream discourse, and that is so beyond twisted I shouldn’t even have to explain why.
If something is part of a living and marginalized religion, it shouldn’t be touched without bringing the whole religion into the work. There’s a difference between taking a long forgotten, dead, or peganism-revived religion and modifying it to suit your needs, taking a dominant religion to suit your needs, and taking a marginalized religion to suit your needs. The first two aren’t really directly hurting anyone, while the last one is deeply hurting someone.
It’s made worse how these creatures/deities are normally cast as monsters, which, as Nikhil said, others the cultures that hold these beliefs. It paints a one sided and very negative picture of the cultures in question. If you’re going to use these creatures, especially as villains, have positive aspects of the culture to counterbalance it.
This really isn’t needed for Christianity or even pagan based religions (in the West, at least), simply because the heroes usually end up being part of the culture they’re fighting against, either explicitly or implicitly. There’s already that cultural balance of good and evil within the work. However, when creatures come from religions that have a less well known spirituality, you end up with some pretty bad unfortunate implications in regards to what “good” and “evil” is.
So if you’re going to cast these parts of specific religions, make sure you’re pulling from both the good and evil side of the religion and taking it within its own contexts.
