That's gonna be a little difficult, anon. There's not a whole lot of mods that enhance the vanilla experience, especially not on source ports that are vanilla.
If you want the true vanilla experience, then you'll probably be best off sticking to PRBoom+ and downloading all the mapsets you can.
If you want something much less vanilla but still vanilla-esque, then Smooth Doom and Perkristian's sounds on ZDoom work wonderfully.
Either way, here, have the usual infographic. Keep in mind only a smidgeon of these will be good for the "vanilla" experience, though.
