In a mixing bowl, whisk together vegetable oil, ranch-style dressing mix, dill weed, lemon pepper and garlic powder. Pour this spice mixture over the crackers in a medium bowl, and stir until the crackers are coated. Arrange the crackers on a large baking sheet.
Bake in the preheated 275 degrees F (135 degrees C) oven for 15 to 20 minutes.
