The Intelligence committees and the FISA Court need to be overhauled, to start with. Clearly there's not enough/proper oversight of the agency.

I don't know how they do it now, but the Intelligence committees should also brief the rest of Congress at least twice a year, and I think they should be allowed by explicit laws to declassify anything they want in that briefing. No approval from the White House or anyone else needed. They are, after all, the ones that are supposedly in charge with oversight of the intelligence community.

So next time someone like Ron Wyden knows the agency is lying to the public, he should be able to tell the rest of the Congress in the briefing, all by himself (he shouldn't need approval from the rest of the committee), and it should be defined in laws that he's allowed to do that, just so there's no confusion, and no fear of repercussion.
