To increase dexterity and speed, you need to practice technical etudes on a daily basis. This will establish muscle and ear memory.
Incorporating scales...it depends on what style of music you're doing. The chord calls during solo sections tell you how the music will be progressing, so it's up to you to interpret the calls and know what kind of scale will be best in that situation. Look up improvisation on popular websites to get instruction, or, just pick up an improv book at a music store.
