This is a support caster build focused on buffs and creating Sneak Attack opportunities for the main character and Mission via stuns. Adapting it to a different sort of caster would mostly mean selecting different Force Powers.

It is worth noting that for the Light Side playthroughs, the last few levels won't matter. Bastila will become unavailable after the Leviathan and, while she's still very central to the plot, she never rejoins as a party member, and therefore won't get to take those levels. Dark Siders get to use her in part of the end game, though.
At the risk of being untrue to the story (Bastila makes some pretty poor choices) I pushed WIS at all opportunities. It does a bit more for her than CHA, and Force Powers benefit from the sum of CHA and WIS bonuses, not the higher of the two.
I didn't specify skills. Class skills are: Awareness and Treat Injury. (Well, technically Persuade, but only the main character can take that.) Unfortunately, neither of those is very useful for the playthrough I created this build for.
Bastila get 5 selected feats. For a melee build, the obvious priorities would be finishing the Two-Weapon and Flurry lines. For this caster build, though, I went with the Conditioning line and the first two Toughness feats.
Bastila gets a reasonable number of Force Powers. This version of Bastila was designed to accompany an armor-wearing Scoundrel/Guardian burst damage one-shotter who greatly leverages Sneak Attack, accompanied by a dual-pistol-wielding Mission, who will also benefit from things that trigger Sneak Attack. So I picked Force Powers with that in mind. A different playthrough style might benefit from different Force Powers.
I did take the Slow/Affliction/Plague and Wound/Choke/Kill lines, for one specific fight (although if it turns out that I even have time to cast them both, then I built my main character poorly).
I intentionally stopped the Force Push line at rank two (Force Whirlwind), because Force Wave seemed like a downgrade by comparision for this version of Bastila. I took Burst of Speed for travel, not combat. Because my main character is wearing armor, it'll be convenient for Bastila to cast Burst of Speed, take the lead, and drag everyone else along. Mostly for those long runs on Tatooine.
I expect this Bastila to wield a blaster pistol rather than a lightsaber most of the time. I don't expect her to do much damage with it. I just don't want the AI rushing her into melee range when I'm not micromanaging her.
