Mayakor’s suggestion for gear is what tanks go for now. If you want to tank in mainly epic elites, then more or less any gear goes, as long as you cover the normal bases (HP [constitution, ins constitution, false life, vitality], AC, PRR, MRR, saves, intimidate, balance). These can be random loot, cannith crafted or named, doesnt really matter from where, as anything goes really.
From your current feat choices, I’d say that you can go vanguard + stalwart or vanguard + kensei + stalwart (for stance) with bastard sword, or kensei + stalwart for two-handed fighting with your epic sos. You dont need a shield to be tanky for non-reaper content though, you can do that while swinging a two-handed weapon without problem (and while being in divine crusader or legendary dreadnought). All it takes is some AC, PRR, MRR and intimidate skill to tank, while swinging away.
Before reaper came out, Denthar was often tanking in legendary dreadnought as there was no need for the extra defenses that unearthly sentinel gave. His feat choices was more geared for dps, as there wasnt really any need for alot of the defensive feats. All it took was a tower shield really to tank, as well as knowing how to move when tanking etc.
