In a medium mixing bowl, combine the steak, soy sauce, garlic powder, onion powder, and pepper. Let the steak marinate for 10-15 minutes.
Preheat a large griddle or a large skillet over medium-high heat. Add the oil to the griddle. Once the oil is heated, add your steak. Cook the steak for about 2 minutes, then stir and cook for 2 minutes.
Add the butter, garlic, and teriyaki sauce. Cook the steak for 1-3 minutes, depending on how you like your steak cooked.
Transfer your steak to a plate and enjoy.
