Might be time to progress the hypertrophy phase into a strength/power driven phase following the new year. You've gained muscle mass, now you need to make it "work" for you. A standard periodization would say to do 6 weeks of powerlifting type training then transition into explosive/power training (olympic lifts) as you get closer to the season.
Keep your calories around maintenance, or just slightly below and you should be able to slowly lean out leading up to the season. Remember, being in a caloric deficit in season is one of the quickest ways to fail.
Thats my advice at the most basic level. We can always go into more detail if needed.
