i dont know how to use chord progressions in metal, like making a chord progression that makes stand out the mode you are using.
First you should know what key you are in and what scale are you using. Could be regular major/minor key, or harmonic minor, these two are often in use. No matter what the progression is, you are using chords that are derived from notes from particular scale. Each of the 7 notes builds one mode and one chord.
In metal you usually use powerchords for rhythm guitar, so just leave out the third interval out of a chord and there you have a powerchord progression within a scale.
Now we get to your question. Usually the lead guitar follows the rhythm guitar, so that the accented notes in the solo or a lead theme are within the chord that is played in the back. The mode you will use during lead playing should correspond to powerchord behind it. Since powechord has only 2 different notes, it's easy to follow the progression and accent those notes.
