SImple and easy. Cash + equity. Equity should be based on a vesting schedule, most common and probably most "fair"
-1 year cliff (no stock vests until he/she is with the company for a year. This prevents bad fits from walking away with a chunk of the company)
-4 year schedule
-Monthly vesting for the next 36 months

This is pretty much the gold standard for tech hires.

The % equity is going to be up to you and the new hire. Ballpark 2-3% depending on a multitude of factors. For a better benchmark, I'd recommend checking out AngelList's hiring product. You can certainly see what other companies are offering in your area in terms of cash/equity.
