We make prayer, as with most things in life, much too complicated.  One of the first things Jesus said about prayer, "Stop with all the vain repetitions" (Matthew 6:7)

Prayer is communicating with God.  You don't need all the Thee's and Thou's; just talk to him as if he were in front of you (he is, after all, inside you).  Okay, that's assuming you've been reborn Spiritually...if you're a sinner, God doesn't hear sinners; so you can say whatever you want.  I should mention, God hears all prayers of repentance, so if you haven't been born again and want to talk to God, repent first.

Jesus almost always went away alone to pray and said "don't be like the Pharisees who pray in public to be seen by men."  "Pray in secret and your Father which sees in secret will reward you openly." (Matthew 6:6)  Even before meals, just bow your head and thank God silently for the food, you don't need to make a production out of it. 

Prayer is a private conversation between you and God...you don't need to pray out loud.  God can hear your thoughts, so you can talk to God anytime, anywhere.

I'm not big on asking for stuff; but the Bible says to make your requests known unto God, so if you want to ask for stuff I leave that between you and God; but when you pray, pray "Thy will be done;" and then rest, knowing that what ever happens is God's will for you.  It may not be what you want...but trust me, God's will is always what's best.

However, until you know, without a doubt, God is real...nothing else matters.
