Combine teriyaki sauce, lemon juice, brown sugar, oil and garlic and stir to mix. Place salmon, skin side down, on 2 layers of heavy-duty foil. Remove thin white pin bones. Baste salmon with soy mixture andlet stand while preparing grill (medium-low heat). Place fish on grill, with lid and vents open. Cook about 30 minutes, basting occasionally, until fish is opaque when tested at its thickest part and reaches 140 to 145F on an instant-read thermometer.
