Do you want your sorcerer to have psychic-like powers or do you want your sorcerer powers to have a psychic origin?
If you go for the first option, then really, any bloodline goes. Just pick spells that have the desired effects and call it day. I suggest the Arcane Bloodline, the most powerful/versatile/less fluff heavy one.
As for the second option... well, there are several answers. How did you character gain these powers? If he got them through a demon, go demonic. If got them from a ghost, undead. Aberrant for a Mind Flayer and so on. There is, however, a 3rd party bloodline simply called Psychic. It's not that great, power wise (it doesn't have telekinetic powers neither, you are gonna have to take the proper spells for that) but the mind reading and divination benefits are ok.
Wayfinder #2 has a Psionic Bloodline, which looks to me like it'd potentially be a lot of fun. I'd say it would fit the bill you've got laid out there.
There is also the upcoming Occult adventures book, if Playtest materials are allowed. But then you wouldn't be a sorcerer so much as an outright psychic.
