My fried rice is too bland, how to make it tastier?

I used two day old rice, frozen peas and carrots, the fried rice seasoning packet and followed the directions on it. All it required for way of flavor was soy sauce and the packet. I tasted it but it was too bland. I added salt and more soy sauce, still too bland.
What else could I add to make it more flavorful? I have oyster sauce, seasame oil and fish sauce on hand. I don’t really like egg in fried rice.
