Startup days are over, how to transition to the corp womb?

I'm making the jump from NewCo to BigCo after being a founder and having a decent exit earlier this year. I'm totally daunted about how to put together a resume, package myself, understand what I am qualified for. I'm doing the usual/obvious stuff (networking, headhunter, career coach, etc...) but looking for pointers from somebody who has made the jump.
