try some stuff by badmarsh and shri, and talvin singh and nitin sawhney. these guys aren't strictly drum and bass producers(they do a lot of mellow asian vibes aswell), but they'd be a good place to start.
check out FabricLive 15 Nitin Sawhney, the later tracks on the album are cool d n b/ asian drum and breaks.
also an album from about a year back called 'Eastern Drum and Breaks' on the Nasha label
a track by DJ Fresh called Temple of Boom has an indian vibe to it, altho it is quite hard d n b.
also there's a new drum n bass producer called amit who does indian type drum and bass. he's got a new tune, very cool, called 'village folk'.
