That requires practice and time.Meditation is one way.There should be some legitimate guides on how to develop your senses on the internet,search (with common sense so that you won't be scammed or do something potentially harmful) and follow whatever guide suits you best.
I believe this guide is quite useful : http://www.wikihow.com/Fine-Tune-All-of-Your-Five-Senses
Also what do you mean by saying awaken your powers?
Do you mean that you want to develop your talents and skills?
Well,its up to you to develop your skills.I can't help you with that,I can only offer small pieces of advice which may or may not help.Anyway,my advice is to get to know yourself.How to do that?Well,that too is up to you.
