Place salmon fillets skin side down on broiler pan. Season with salt and pepper.
Broil 10 to 12 minutes or until fish turns opaque and is cooked through. Separate salmon into chunks with fork; cool slightly. Discard skin.
Meanwhile brush cut sides of bagels lightly with oil; sprinkle evenly with garlic powder and cheese. Place in single layer on baking sheet. Broil about 2 minutes or until toasted.
Combine mayonnaise and dressing in large bowl. Add salmon and lettuce; fold gently to combine.
