What are good foods for a small guy trying to pack on some extra muscle?

Im looknig for a few good diets for myself... im very small comming in around 5,5 and weight only 130 but i do have some muscle packed on but im looking for that extra edge to my tone...you know like most guys they wanna be big. but im not trying to get you know prisoner big. i was told that for a small guy like me i have a high metabolism and i need to consume more protein and calories to aid in muscle production.. i work out almost everyday and have been doing so for a few months now and havent really noticed any slight change so i figured it was my diet. what would be some good exercises and diets for a guy in my status? I would like to look good before i start my final year of school.
