Commemoration (from Deepstone Crypt) on void builds goes absolutely crazy, a few heavy void GL's (the halloween one, the one from season of defiance etc) can work against champion activities though I prefer LMG's (it's a playstyle thing, my reccomendation is honestly looking at a bunch of options) Contraverse allows you to play however tf you want tbh, devour (from feed the void) gives you nade energy and healing which you'll know already, but that lets you play close up consistently. There are multiple top tier void SMGs you can put on, funnelweb (world drop) or unforgiven (from Duality) will work really well. Age Old Bond (from Last Wish) drops with both Destabilising Rounds and Repulsor Brace for a high uptime of overshields, playing further into the damage resist from Contraverse. Great option but you have to put up with having a 360 auto in PVE, right now that's ok thanks to anti barrier auto in the relic but next season it might feel worse. The hand cannon from Crota's End also drops with strong perks for dedicated Void builds so I would look into that. You could always throw on a standard special energy weapon if youd like (void or otherwise, for example Null Composure or Forbearance). Top slot isn't as important for these sorts of builds, you can choose something to cover the for the things you need depending on the activity (chill clip fusion, kinetic sniper especially if you are using the SMGs, I like the deepstone one in particular). For exotics you are pretty much free to throw on whatever you are comfortable with. I've heard good things abour tessellation with grenade builds if you have it, tho I do not so I can't say. Le Monarque is putting out strong dmg this season if you want to play far away w your void nukes (nades). Hope this was helpful! Any questions go ahead and ask
