1) Taking measurements so you can monitor all body changes.
2) Setting up a lean bulk eating plan; something you can live with for 2-3 years.
3) Focusing on getting as strong as possible on the quality exercises.
If you need a change of pace as far as routine, maybe try Bulldozer training. I have found this style to be very effective for muscle building.
You can find more here:
There are many more quality options. As a late intermediate lifter you might want to try an upper/lower split.
cheers bro al looking into that stuff bulldozer training looks quite good
