Hmm... Get rid of Glyph of spiritual attunement. It really doesn't do much, Glyph of seal of vengeance is generally more useful.
To some extent, if your survivability is too high, it will hurt your mana generation. Usually, the following are good rules of thumb:
Always Judge Wisdom if it's not up.
Maintain Divine plea whenever possible. Pop it before the pull. Save critters.
Don't consecrate if you think mana will be a problem. Consecrate is a huge drain on your mana pool.
Blessing of Sanctuary is better than BoK if you can't have both.
