The following are feats that I made up.  Feats designated with a "*" can be taken as fighter bonus feats.

Cautious Charge^*
You are adept at charging with out compromising defense.
    Prerequisites: Base attack bonus +3
    Benefit: When performing a charge action you receive no penalty to your armor class.
    Normal: After a charge action you receive a -2 penalty to your AC for one round.

Reach Weapon Expert^*
Choose one weapon with a 10 foot reach.  You are now so adept in the use of this weapon that you can attack foes adjacent to you as well as foes 10 feet away with equal ease.
    Prerequisites: Base attack bonus +3, Weapon Focus in chosen reach weapon.
    Benefit: Choose one weapon with a 10 foot reach.  You may now strike adjacent foes as well as opponents 10 feet away with it.
    Normal: When using a reach weapon you can only strike foes 10 feet away (with the exception of the exotic weapon, the spiked chain).

The following feats are taken from the Book of the Righteous.  There are more feats in the book but these are the only ones I really like.

Free Thinker
When you take this feat, you are freed from aspects of traditional church dogma and ritual, and may pray for your spells at any time of day.
    Prerequisites: Wis 13+, Clerics only
    Benefit: With this feat, you may prepare divine spells at any time and any place.  You must still follow the "Recent Casting Limit" rules as explained on page 156 of the PHB. The effect of this feat is that you may ignore the "Time of Day" rules on the same page and may pray for your spells whenever you like.

Heretic
You hold views deemed deemed heretical by your church, but you still gain spells from your god.  This feat explains how heretical cults come into exhistence.
    Prerequisites: Cleric
    Benefit: The cleric may be two alignment shifts from a God's alignment and still receive powers from that god. A heretic may be neutral if the sponsor god is one alignment shift from neutral.
    Special: A heretic receives the same domains as other clerics of the god, but may not take alignment domains counter to her own. Whether the heretic is actually receiving power from the God he professes to worship is up to the DM. If your DM defines a heretical cult, you might receive different domains from the cult than from the usual church of the God.

Profound Faith
You may not be the brightest holy symbol in the temple, but your faith is stronger than most. You use your faith more than your wisdom to call for aid from your god.
    Prerequisites: Cha 13+
    Benefit: You may use your charisma instead of your wisdom to determine what level divine spells you can cast and the number of bonus spells you receive.  You continue to use your wisdom modifier to determine everything else about your divine spells, such as DC for saving throws against them.
