Slice steak into 1/2-inch thick slices across the grain.
Whisk together soy sauce, sugar, cornstarch, and ginger in a bowl until the sugar has dissolved and the mixture is smooth. Place steak slices into the marinade, and stir until well-coated.
Heat 1 tablespoon vegetable oil in a wok or large skillet over medium-high heat, and cook steak strips in batches in hot oil so as not to crowd the pan. Cook and stir until well-browned, about 3 minutes, and remove steak from the wok to a bowl. Repeat with remaining steak, adding more oil as needed, and set the cooked meat aside.
