In the medium-sized mixing bowl, combine garlic powder, onion powder, soy sauce, Worcestershire sauce, salt, and pepper. Mix well.
Marinate the deer steak overnight for best results. If you find yourself short on time, you can marinate it for an hour. Make sure that every piece is sitting nicely in the marinade.
Remove the deer steak from your refrigerator, and let it reach room temperature.
Heat olive oil in a skillet.
Transfer the deer steak to the skillet, and cook on medium-high heat, checking with your meat thermometer.
Flip the pieces every once in a while to make sure both sides are evenly cooked.
While cooking for approximately five minutes will result in a well-done deer steak, you can always cook for 3-4 minutes for a medium-done steak.
