There is no way to simulate the CG differences between a trike and a dragger, and that difference is what's most important between the two.
Landings are where the greatest potential for damage exists. Trikes let a pilot get away with sloppy landings and sloppy directional control, draggers do not. That seems like a great place to start.
Make your landings precise, absolutely straight with zero drift. Land with the nose wheel off the ground and keep it there as long as possible.
Only use a forward slip to control drift on approach and with crosswind landings, no crab approaches. Even though you can crab a dragger on approach, you'll have to transition to a forward slip before touching down. You don't need crab practice.
Of course you have to take off before you can land. Treat all your take offs, in the trike, like soft field. Get the nose wheel off immediately and complete the takeoff roll on the mains. Like the landings keep the takeoff roll absolutely straight with zero drift.
While taxiing keep 100% of your attention on taxiing, don't adjust trim, fiddle with radios, iPads or anything else. You might be able to get away with that in a trike, but in a dragger, especially one with a high deck angle, you'll dart off the taxiway or even ground loop.
Hope this helps, and welcome back to aviation!
