I would think that this would be a good LC moveset for Vulpix:
Vulpix @ Heat Rock
EVs: 52 HP / 196 SpA / 236 Spe
- Heat Wave
- Solar Beam
Heat Wave is STAB, Solar Beam is coverage that doesn't require charging thanks to Drought, and Will-o Wisp is to cripple psychical attackers. Protect helps rack up damage from Will-o-Wisp . You could also replace Protect with Hex, and take advantage of burns.
