I haven't found much, but here's what I've found so far:
General (paid) web directories with a decent India Regional category:
DMOZ (free), Yahoo!, BOTW.org, AvivaDirectory, Directory.v7n.com, Romow, AuthorityDirectory, Webotopia.org, In.Ezilon.com, HotvsNot
There are a number of free Indian web directories that I found through Google searches. I submitted my listing; after 11 days I still haven't heard back nor has my listing been approved. One exception: IndiaWebDirectory.info added my listing.
