In particular see the lessons on the triads that result when harmonizing the major scale.

I'd suggest that if you get a firm conceptual grasp on the triads that get built when you harmonize the major scale (the first mode - ionian), then all the rest is a matter of shifting the root note.
[QUOTE=jimmynitcher]
If I pick G Dorian and build a triad from the A in its scale I get A, C and F.
No, you would get A, C, and E.
If you want to build triads in G dorian, then the first thing you want to do is realize that G dorian is simply F major (ionian). So, the notes are:
F major (ionian)
F - G - A - B-flat - C - D - E - F
Therefore G dorian is simply F major starting on the second note:
G - A - B-flat - C - D - E - F - G
For future reference also see this tutorial is on triads:

Hope this helps, let us know how it goes.
