I was under the impression that the stripping was permanent, hence the NO! vote. Temporarily, atonement is in order, but with the paladin keeping his powers in the interim. Sorry about the apparent incongruity.
The rules for paladins regaining their lost powers are unfortunately rather complicated, and seem to be inconsistent, at least in PHB 3.0. Perhaps they were cleaned up in 3.5.
If the paladin loses his powers through a wilful, knowing evil act can never regain them. (According to the
Atonement spell description).
A paladin who willingly but unwittingly commits an evil can have the powers restored by an
Atonement, which will cost the caster 500 XP. The caster may chose to impose a penance befroe agreeing to cast the spell.
A paladin who loses his or her powers through committing a gross breach of the code of conduct or through associating with evil characters can presumably have them restored by getting a cleric to cast
Atonement on his or her behalf. If the breach was a willing act it costs the cleric or druid 500 XP to cast the
Atonement, but if it was an unwilling act it has no XP cost. (I am not sure that I would ever rule an unwilling act to be a gross breach, but that's beside the point.) It is up to the discretion of the caster of the spell to decide whether to impose a penance, not part of the spell or a decision of the god. If the character gains a level before atoning he or she gets his or her powers back but can never again raise his or her paladin level.
A paladin who loses his or her powers by ceasing to be of Lawful Good alignment must restore Lawful Good alignment either through extended consistent play or by use of the "Redemption" version of the
Atonement spell. My ruling would be that the powers then spontaneously come back, but some GMs might require an
Atonement. If the ex-paladin gains a level before regaining his or her alignment (and
Atonement, if the GM rules that it is required) the powers come back but the character can never gain another paladin level.
I'm not going to defend these rules, which seem rather arbitrary and in some respects pointless, besides which there seems to be a mistake in either the Paladin class description ot the write-up of the
Atonement spell. And things may be different in the Realms. And of course any use of Rule Zero is beyond what we can contemplate. But as the rules stand the question of whether and how Vindicators character can get his powers back depends on the ruling under which the GM stripped them away (if, indeed, the GM decides to stand by his decision).
