The easiest path is to just do it. You as an owner can easily describe a profit sharing scheme in words and act it out in actions. There is no legal anything to do. You just give people the money as bonuses.
Another strategy is to split controlling stock from equity stock. Most public companies do this now. So for example, you can define that
Class B shares get 10 votes per share while Class A shares get 1 vote per share. That way you can maintain a small ownership in the company but still have a controlling interest. Currently people do this for nefarious reasons, but you could just as easily use this structure to distribute dividends. There are tax complications this route (when gifting shares or offering an options incentive package) — but at the same time, dividends are taxed far below anything else in America.
Honestly, I'd just go with route number one. Just do it. Nothing complicated.
