I haven't seen too many in American zoos. I'm guessing the shortage of large carnivores and primates truly native to the Indian subcontinent in AZA programs and in American collections in general might be part of it.
Most of the big draws from Indo-Malaya the AZA works with are Southeast Asian like Sumatran tigers, orangutans, gibbons, sun bears, etc. so that's most collections' tropical Asian theme of choice. But personally I think we have more than enough relatively numerous species to work with. Asian elephants, Indian rhino and several ungulates are all in decent numbers, along with flying foxes, peafowl and numerous reptiles. Sloth bears and dholes aren't as common here, but small carnivores like fishing cat are also somewhat present. Lion-tailed macaques are a distinctive primate as well. Elephants, sloth bears and maybe rhinos are the only big crowd pleasers but that's a great 'supporting cast' right there. (Although, with all the 'generic' tigers you'd think some would have been featured in this theme more often. And it doesn't seem to stop European zoos from including non-Bengals.)
If it's not all Southeast Asian you usually just see generalized 'Asian' areas that focus on Indo-Malaya in general, maybe throwing in the Himalayas too. At times you do see an Indian motif heavily supplanted with out of place Southeast Asian species such as Disney's Maharajah Jungle Trek, with Komodos, white-cheeked gibbons, banteng, etc.
