Find a venue
Pick a place outside that can accommodate a lot of people. Maybe a school sports field (think baseball or football field).
Hire a local band to play or get art students to display artwork relevant to your cause.
Talk the talk (but not too much)
Give a short speech for everyone who is there. Prepare something to say, thanking people for coming, and explaining what the vigil is for and what it represents. See if you can get people to hold a candle and each candle can represent a statistic. Like if your cause is Darfur, each candle can represent 1,000 lives already lost in Darfur.
The candles, that is. Have it be silent, and let the candles burn for five or ten minutes for people to get the full effect. After a few moments of silence, announce again to the people the need for action to be taken. Hopefully, at this point, they will be moved and motivated!
