Zeshan if you cant find any paid job consider the fact to be a freebie for a couple of months. i was a freebie for 4 months in my company before i was offer a position. This way you will be in the industry at least and possibly get a recommendation from someone.
A good place to start is base maintenance station were you will see the aircraft stipped down and work down all the aspects of the aircraft.
as for the log book try the caa one which i think is this

and remember speak to all the mechanics and engineers and i am sure someone will show you the way around the industry
