You want your cheese against your bread, preferably on both sides because that is your glue and without it, your panini will not stick together. You want to minimize ingredients with a lot of liquid, like fresh tomatoes. If you use tomatoes, cut or squeeze out the seeds (and juicy stuff that surrounds them).
You don't really need mayo because of the cheese, but if you want it for flavor, put it inside the sandwich not between the cheese and bread.
The lettuce will only wilt when it's heated, so you'll want to pull your panini apart and add the lettuce after you grill it if you must. Lettuce is more of a fresh sandwich ingredient, not a grilled sandwich ingredient.
Don't use foil. If you're concerned with sticking, use a little olive oil in your panini plates or on your bread.
