First off you're gonna want an unofficial patch for the base game.
Then you're gonna want VRIK, which gives you a proper body and holsters and also has magic gestures and shit (although another mod, magevr, is better for magic gestures so get that as well).
Then there's HIGGS, which gives you gravity gloves but also more importantly gives your hands proper physics and lets you pick shit up properly instead of just point and clicking like the base game.
For sound you'll want "true 3d sound for headphones", there's also another popular one for the same thing but I haven't tried it out yet.
And with that I'd say the basic setup is more or less done, you've now made skyrim vr into an actual vr game. There's some extras you can slap on top of that though:
The before mentioned magevr which changes how you not only select magic but items as well and can also change how you loot, how you lockpick and lots of other things, it's a big mod.
There's please be seated which gives you a loading screen when you sit so you can reposition yourself.
There's navigate vr which gives you maps you can hold in your hands and if you combine it with some other mods that the author recommends in the mod page you can play the game without ever relying on it's native map or compass.
There's lots of graphics mods, both bigger ones but also one that don't change anything too fundamental and just make the game look better, I won't bother listing those though because there's a lot and it's largely up to preference.
Oh and you'll want skyUI, although I think one of the other mods I mentioned would probably have forced you to install it anyway.
