～ずに
without
朝ごはんを食べずにオフィスに行くと、疲れますよ。
You’ll get tired if you go to the office without eating breakfast.
若い頃は何も考えずに、思うことを全部書いた。
When I was young I wrote down everything I was thinking about without thinking.
So for verbs it’s actually ない form of the verb but remove the ない + ずに. It’s that my verbs used here are all Group II words so it wasn’t obvious.
