I have a Veela Tag here, where it's also tagged which fics are bottom!Draco (careful because when also tagged Bottom!harry it means they switch).

As for the Alpha Harry/Omega Draco:

The Songbirds of Avebury Manor by Tessa Crowley (AU)
Hundreds of Tomorrows by snugglemint (werewolf)
I Was A Teenage Werewolf! by treacle_tartlet (werewolf)
Rejoicing in Their Strength & sequel Eyes That Can See in the Dark lomonaaeren (werewolf, warnings)
Tuxedo Angel by tryslora
Burning the Ground by traintracks (knotting, not quite alpha/omega, but seriously, hottest thing ever. :D)
