In a large shallow dish, combine soy sauce, Worcestershire sauce, liquid smoke, garlic powder, and onion powder. Mix well. Season the steak with salt and freshly ground black pepper. Place the steak into the marinade, ensuring it is evenly coated. Marinate for 20 minutes at room temperature or up to 24 hours in the refrigerator. If marinating longer than 1 hour, bring the steak to room temperature 30 minutes before cooking.
