A small gazebo is nice, especially if it's gonna rain. May I suggest EZ-Up. Also, depending on what you're cooking, you'll definitely need a grill and possibly a turkey fryer. You can make wings, fries, or anything else in a fryer. Another essential is Cornhole. Buy a set or build your own, you'll be glad you did! A table is nice for preparing food, and setting up a little buffet. You can also clear it off later and play beer pong. You'll also want some seating, whether folding chairs or a couch. If you really wanna go all out, you can get a generator to run the TV, stereo, and blender. Let's see if I'm forgetting anything. Oh yea...Da Beer! (Note: Either finish the beer before the game, or lock it up when you go in, IT WILL GET STOLEN! -- We've learned our lesson).
