What's the most efficient way to plan a one-shot TTRPG adventure?

I'm a bit of a fan boy for the 100 one shot wonders book. I've run the previews and really liked them. The session I run the LFGS doesn't have the player consistency to run multi-session adventures. These work much better than the Adventurer league ones.

Otherwise, I use the '8 steps of the lazy dungeon master' from 'return of the lazy dungeon master'. I like it when I can do role play and problem solving scenes, not just combat. The other thing is keeping to a low level and small scale combats.

I've researched The Lazy Dungeon Master online in the past and love some of his ideas. One of these days I am getting those books!
