Admonition Angel would work...drop a land to exile Barren Glory, then cast Kaervek's Spite afterward. Everything will be sacrificed to the Spite, and Barren Glory will return as Admonition Angel dies. Oblivion Ring is a cheaper option to do the same thing. Your basic strategy should be to stall the opposition long enough to get everything you need in play. The Angel has the bonus of being landfall-based removal, so after exiling Barren Glory, you can still use it to get rid of problem permanents your opponent controls (just don't exile anything aside from Barren Glory from your side of the battlefield). As for lands, since both spells require more than one colored mana each, make sure you're running plenty of dual lands, or cards that can filter mana for you (personally I like Chromatic Sphere for the card draw, but there's plenty of other options as well...go with what suits you best). One well-placed Dark Ritual will also be able to trigger the Spite as well, so I'd include at least a couple of those as well, just in case. Also, throw some Tutors in as well, be it Demonic, Vampiric, or whatever...getting what you need when you need it is essential, assuming they would be an option for you (restricted in Vintage, banned in all other formats). Barring that, anything to either draw cards or shorten the deck will help. Fetch lands can help trim the deck down to the essentials, Land Tax can be used for the same purpose...even if you don't need the lands, it thins the deck out so you get something a bit more useful to you in your draw step (conveniently, you draw after your upkeep, so it'd be your deck minus three lands). Scroll Rack may be another viable option.
If I were running a similar deck, I'd try using this as a core for the deck.
4x Admonition Angel
4x Barren Glory
4x Kaervek's Spite
4x Dark Ritual
4x Land Tax
4x Oblivion Ring
4x Enlightened Tutor
I'd fill the list with low cost creatures to help defend until you are set up fully for the win, maybe some life gain (especially recurring life gain) to keep you alive, and a bit of mana ramp and/or card draw. For the lands, assuming you build the deck heavily as white with a splash of black, I'd keep it geared more heavily toward white, but with enough black to get the Spites out. Really, it could be all white save for three swamps and you'd be golden, because as soon as land tax triggers, you could pull your three swamps to your hand and go from there.
I hope this helps to at least give you a starting point for the deck. I'm actually kind of looking forward to seeing what you come up with
