Register your .in domain with Google webmaster tools, and there is a section there to geotarget India. The thing is, it shouldn't be necessary because Google has already expressed that country-specific domains such as .in are already targeted to their individual countries. But it can't hurt.
It might also help to cross-link between your two sites, if you're not doing that already. I suppose that each domain would need its own individual set of backlinks, as well.
