Honestly, I think you will have a hard time getting into your target schools. Your GMAT score (okay but not amazing), Indian background (which unfortunately puts you in a very competitive group), and lack of ECs will all make it hard for you.
Also, why are you looking at getting an MBA now, after being in banking for seven years? While this fact doesn't automatically kill your candidacy, a much more typical banker profile is to apply with 2-3 years of experience. You will really need to convince admissions officers why you want an MBA now, when many of your peers went off to b-school several years ago.
I would suggest taking another crack at the GMAT and aiming slightly lower in terms of where you want to get in. Especially if you want to get into strategy consulting, you can go to a school like Darden or Fuqua and still have a shot at the top tier of MC firms.
