You are coming from a large applicant pool (Indian, Male, IT), but you have a great GMAT score and decent work experience. As you correctly identify, the lack of mgt and leadership could be your achilles heel. What you want to do is dig deep in your experience to see where you have demonstrated at least leadership potential (have you lead a project, for example? been on a team where you had increased responsibilities?). Everyone can generally find ways to show some sort of leadership. At the very least, you need to get some real advocates at your employer to go to bat for you on recomendations, so that they can identify you as a top performer among your peers and someone in whom they see much potential to lead. Good luck.

Bryant, Thanks for your input. About the other part of my question, can you suggest me some colleges in Europe where I will stand a good chance of acceptance?

With a 710 GMAT, I would still target the top schools in Europe and go to the best school you can get into. All the usual suspects are fair game: HEC Paris France; London Business School, UK; Insead, France; IMD, Switzerland; IE Business School or Iese in Spain; Rotterdam School of Management; Erasmus University, Netherlands; Lyon Business School, France; Esade Business School, Spain; Vlerick Leuven Gent Management School, Belgium; Essec Business School, France; ESCP Europe France / UK / Germany / Spain / Italy ; City University Cass, UK; Cranfield School of Management , UK.
