First, read the how to bulk sticky. Then look at a beginners strength routine like Rippetoe's Starting Strength that emphasizes the big 3 compounds (squats, deads, bench) and less on isolations. I noticed your routine does not have these movements and they are guaranteed mass builders.
We would also need to see your diet in very specific amounts. I would bet you are not eating enough. Anyway post up the diet and research some and we will get you on the right track.
