Im thinking about financing a small business....?

What terms do venture capitalists usually loan money on. What % of profits do they usually take, and for how long? What type of repayment plan to they have for the money borrowed?

Hope you have money to lose. Most small businesses go under!
But, if you still want to loan money to a small business, I would think you would want to see some sort of business plan. Most businesses don't plan to fail, they fail to plan.

Negotiate what your money is worth. If you invested it elsewhere, what would be it's return on investment. Use that as your base. Remember, investing in a small business is really risky, the returns should be higher than normal, just don't may it too high, you can be charged with Usery charges. What are they willing to put up as collateral for the loan. Caution, check with your local athorities, if you receive % of profits, you might be considered part owner even though you have nothing to do with the day-2-day operation. That might leave you liable in some way...

It depends on the type of business and the amount of money borrowed. Basically you will have to negotiate until you feel comfortable.
