There are plenty of good recipes on the recipe page here
look through them, and choose one you like. I did one close to this
for my first batch except I added 2 cups of cane sugar to boost the abv and only had bread sugar to use, and it still came out fine. (I dont suggest using bread yeast though). They are all fairly flexible, and as you are using a keg, and probably force carbing you dont need to worry about bottle bombs like me, which is the most difficult part.
