When I perform outdoors, I sound distant and thin, and I'd rather sound pretty much "in your face". How do I achieve that sound? I play with a country rock group, strong vocals, fiddles and electric guitars and drums.
Put up a wall behind you. The audience will be in front anyway, so there is little point in blasting out your behind. Stand on a stage with a hard floor: no need to make the ground shake: just brings out the earthworms.
The neighbors will also appreciate if you can deal out your sound energy more focused on the audience since then it will not be as loud outside of audience coverage. So basically you need a stage with a floor and back panels.
You've got used to the sound being reinforced by bouncing off the walls of a room. Outside, that won't happen - though you might get a slap echo if there's a wall or building in the vicinity.
You can turn the bass up. Add some reverb. Surround the audience with PA speakers rather than just having a couple set up at the front.
If you do home recording, learn the lesson of how much you're hearing the particular ROOM you're in while mixing.
