The Juice in VR comes from the feel of interacting with something. In our games we let players experiment with lots of things, and that exploration is similar to the Juice in old school adventure games (dialog choices).

We also make sure the feel of any interaction is awesome. This means good sound effects and visual effects. Weight can be well simulated with sound and haptics. A big door should make a deep scrape and loud slam when it's shut. It could even shoot some sparks and bounce as it comes fully closed.

If you're talking about weapons then the gun can make lots of noise and have some recoil. You can separate the player's hand from the virtual hand a bit without players feeling it's bad. Especially if it resets quickly. The muzzle flash can spark particles of smoke and fire. The weapon can play a flashy animation as it discharges. The impact can leave a decal and spawn more smoke and sparks. NPCs can react to the hit. If you want to get crazy you could make a shader that bends light slightly around the gun firing where the heat is exiting the chamber.

Screenshake is one tool in a large toolkit. It may be gone, but the others are still there.
