I'm hopping in late here 
Did we define what god we're talking about here? If it was the god of the bible I'd seek a way to defend myself and my friends/family from his insanity, whatever it takes.
If it was just a deistic creator god I'd hope for the chance to have a drink with him sometime, I'd like to meet the god that started everything off then just observed. I could learn a lot.
Either way, there would still be no prayer or worship, my life would either carry on as normal or I would seek ways to kill the god to protect everyone from his insanity.
