I'm playing a fire elemental (race and bloodline) blaster sorc, gestalt multiclassing with oracle of flame. My racial traits and favored class bonuses give me half my level to fire damage spells, count me as two levels higher when calculating number of damage dice with fire spells, allow me to turn any non-fire elemental spell into a fire spell, and give me +2 to my Cha when calculating save DC for my fire spells. And I have a permanent 27 Cha before those bonuses. Basically, I am *really* good at burning the crap out of everything flammable in sight.
Unfortunately, because I'm so completely focused in fire, I'm also rather helpless whenever I have to go up against anything with any kind of resistance or immunity to fire damage. And half dragons are one of the most common enemies in this world. What can I do make myself better at fighting fire resistant creatures? Is there a spell out there that gives vulnerability to an energy type, or removes present energy resistance/immunity? Or a feat that lets me turn fire spells into other kinds of spells?

The metamagic feat Elemental Spell is what you are looking for. +1 to spell level, change your elemental damage type. The downside of this is that you pick which element you can change to when you pick the feat, not when you use the feat so you are locked in. I'd go with Acid as it seems to be the least commonly resisted element, but Cold could maybe be workable as you at least have what fire heavy foes are weak to now.

I know for Cold, there's Truefrost Elixir. I don't know for fire, but there should be something if you look hard enough.

Thank you! Anything else I can do to make myself a bit more versatile?
You could consider a dip into Admixture School Wizard; that would let you change your elemental type on the fly to whatever you need 3+int times per day. Normally that dip would hurt a lot as a spontaneous caster, but if you are playing gestalt it hurts a lot less. Loss one level of Flame Oracle progression for it and be good to go.
