In a shallow dish, whisk together flour, garlic powder, salt and pepper.
Coat both sides of each cubed steak in flour mixture.
Add more oil to skillet over medium heat.
Cook each steak about 5 minutes for each side (until no longer pink inside).

If you want a thicker gravy, add 2 tablespoons of flour dredge to skillet and stir into grease to make a roux.
Use a whisk and add about 1/2 of the broth to deglaze the bits stuck to the bottom of the pan.
Add onion soup mix, remaining broth and fried onions.
Cook until hot and thickened.
