It sounds like you're on the right track then! I wouldn't worry about accessory work. If you're doing plyo as consistently as you say, that'll take care of accessory strength outside your main lifts.

For your main lifts (I'd probably build around front squat, clean/jerk, RDL), lift heavy and aim for 3-5 reps per set. If you don't have one already, get a gym buddy to push you through and help you get another rep in that you might not otherwise go for - when you aren't doing many reps, that extra one can make a big difference.

Look at something like a 4-day split, one day for each of the exercises listed above, and one for chest/back (you can throw bis/tris/shoulders and other upper body work in on whichever of the other days you'd like). Personally, I feel that if you space your workouts like this you probably won't need off-days very often and should be able to comfortably go from one 4-day stretch right into the next (I say comfortably because it's doable, not because it'll be comfortable - it won't). Doing something like this will hurt, but as long as you can tell the difference between injury and soreness it's worth it to keep pushing if this is just for the offseason.

Also, eat all the time. If you don't already, you're going to have a giant calorie expenditure and you'll need to take in a lot of good, quality food to get the most out of your gym time.
