Cut tofu crosswise into 12 (1/2-inch) slices. Place tofu slices on several layers of heavy-duty paper towels. Cover tofu with additional paper towels. Place a cutting board on top of tofu; place a cast-iron skillet on top of cutting board. Let stand 30 minutes to 1 hour. (Tofu is ready when a slice bends easily without tearing or crumbling.) Arrange tofu in a single layer in a 13 x 9-inch baking dish.
Combine juice and the next 6 ingredients (juice through garlic) in a small saucepan, and bring to a boil. Cook 1 minute, stirring until honey dissolves. Pour over tofu. Cover and let stand at room temperature 1 hour.
Remove tofu from dish, and reserve marinade. Coat tofu with cooking spray. Place tofu on grill rack coated with cooking spray. Grill 3 minutes on each side or until browned.
Remove 12 large outer leaves from lettuce head; reserve remaining lettuce for another use. Remove bottom half of each lettuce leaf; reserve for another use. Place 1 tofu slice on each lettuce leaf top. Top each leaf top with 2 teaspoons cilantro, 3/4 teaspoon peanuts, 3 mint leaves, 3 carrot strips, and 1 basil leaf. Wrap leaf around toppings. Serve with reserved marinade.
