The lorebook section on the history of Allag has the key to this, I think.

From page 27, "Victory in Meracydia", it talks about their pact with the voidsent, and that it specficially involved summoned voidsent fighting in the Allagan army. Any enemy they killed could then be immediately used to summon another voidsent into the body, thus expanding the army. Effectively the zombie analogy you were talking about.

So I think that's what's happening in Haukke Manor as well. The Wood Wailers aren't just being corrupted, they're being killed and immediately taken over by whatever voidsent they "transform" into.
