I do mostly the same as Victor described:
cut the backbone out and smash it flat. Marinade in a 1 gallon ziplock bag with olive oil, salt, pepper, soy, pineapple juice (ala el pollo loco), garlic, a dash of liquid smoke and diced onions. Let it sit in the fridge for at least an hour, I like 4 hours.
I tie up the wings and legs (tuck em in) to keep them from getting burned. Microwave for a couple of minutes to get the bones warm but not hot. That helps get everything thing cooked evenly. I hate trying to cook meat fresh out of the fridge (cold) because the insides take too long.
I grill over medium heat on my natural gas grill and only flip them once. Constant flipping dries out the meat.
