We avoided simpering Disney princesses (prevalent in the 2000s) and she's a fierce wonderful feminist. 
I worked full time in a male dominated industry and kicked ass, and showed her that as an example (she saw the struggles too). We talked about the barriers I was clambering over, the inherent sexism, blatant discrimination, and the sheer elation of the victories achieved in that climate (victories that also helped pay for nice family holidays ).
Me and DH shared equally all of the domestic stuff and mental load. Equality in action, every day.
We told her that she could do anything and that every opportunity was (is!) open to her. Boobs are no barrier.
We helped Instill confidence in her so that she could vocalise her opinions and earn respect without being domineering. We also helped to to learn how to listen and have empathy.
When she was (physically and mentally) bullied at primary school we did role play to help her stand up to the bully (it worked) and to show how powerful standing up for yourself can be (and a bit about why that person was bullying her and that it was probably a cry for help and attention).
Most of all we loved her and told her wonderful she was (and is) and let her find her own path. She's well on the way to that now and is a pretty fabulous human. Confident (but not too cocky), strong (but gentle) , helpful (but not a doormat) , kind, empathetic, creative and with high hopes. She's had her ups and downs (some quite low) but on the whole I think it's been OK.
Oh, and we banned phrases like 'bossy'. It's only ever used for girls and women and is inherently sexist. We say 'strident' or 'in control' or 'being a leader ', which are all positive. Language is so important.
We challenged and thought about sexist stereotypes right from the get go. It's really easy to fall into the pink, Barbie route without thinking. We offered up alternatives so she could choose. She ended up choosing cars and Barbies.
We brought her brother up exactly the same.
What I'd do differently? Take more time and have more patience with the tantrums (fierce and frequent !) and let them run their course more naturally . I squashed them down a bit too vigorously
anger can be good. Sometimes
