Chickens are great lemon pepper style. I've cooked dozens of chickens on the grill (and one in my smoker, I'm a newb) and I'll give you another chicken recipe.
Take the chicken and rinse it under water, pat dry with a paper towel, cut a lemon into the thinest slices you can and coat both sides of the slices with cracked black pepper. Take a pearing knife and cut a couple holes big enough into the skin to stick your finger in without punchering the meat. Roll up the slices loosely and insert the lemon slices under the skin, and move them so they lay flat between the skin and meat. The trick is to cut the least amount of holes, so you can get 2-4 slices under the skin per hole. Then rub the whole chicken in EVOO and leave it be, or coat with your favorite rub. Smoke til about 165° and remove, (the temp will rise a bit after to remove it from the smoker) enjoy!!
