I agree with googling.
There seem to be a couple approaches to giving a toast. One is to recite some short poem which itself is in the form of a Toast; the other is to tell a short anecdote about the individual, preferably not too intimate, preferably related to the event, and rounding it out by asking everyone present to raise their glasses and joining you as you say, "To Jim" (or whatever his name is, obviously).
Some people, confusing "toast" with "roast" make the anecdote a bit too personal and choose one which also isn't true but which they hope will be entertaining to the crowd. That's rarely a good idea.
One example that comes to mind was from a wedding, where the step-daughter of the groom spoke for a minute about the annual family trips, and how it was during one of those trips that she realized that when the time comes, the Groom was the man whom she wanted to be giving her away at her own wedding. Please join in raising a glass to Jim!
It was personal, very positive, relevant to the event, highlighted the object of the toast, and only took barely a minute.
