For India service providers you will have more choice on Hunqz. For regular meet ups, try Planet Romeo. These two are the most popular in India.
You can also find the gay parties on Facebook. There are almost no gay clubs or bars (except maybe?? Mumbai), but there are weekly parties in clubs/bars.
if you want a gay travel service and private intro to guys and parties, then you can contact IndjaPink, a travel service focused on lgbt travel in India. See http://www.indjapink.co.in
