Highlights
Eldritch Glaive requires a touch attack to hit, allowing you to Power Attack for added damage.

Strength Domain allows use to use wands and scrolls of Enlarge Person to go large multiple times a day.

Battle Caster allows you to use your invocations while wearing heavy armor.

With 17 starting strength after racial mods, your strength will be 17 + 5 (level) +1 (bloodline) + 5 (tome) + 6 (item) = 34 when not enlarged at level 20. Full attack (every attack is a touch attack) will be 12 (Str) + 12 (BAB) - 12 (Power Attack) + 1 (Weapon Focus) + 2 (Melee Weapon Mastery) = +15/+9/+5, with damage being 18d6 (Eldritch Glaive + Hellfire Blast) + 2d6 (Greater Chasuble of Fell Power) + 18 (Two-Handed Weapon Strength) + 2 (Weapon Specialization) + 2 (Melee Weapon Mastery) + 24 (Power Attack with a two-handed weapon) = 18d6+44 or 98 on average. Should all attacks hit, that comes out to 294 damage per round on average.

If you drop a foe, great cleave allows you a strike against anyone within your reach.

Maximize your eldritch blast to deal 164 damage per attack.

At higher level, vitriolic blast bypasses spell resistance.

Further Optimization
Find a way to gain haste for another attack per round. Extra Dex allows more AoO's, as well as boost your reflex save.

Limitations
Low hit die (mostly d6's) means you'll be rather squishy for being up in melee.

Lower warlock levels means Spell Resistance can cripple the build until you gain vitriolic blast.

DM Counters
Creatures that can teleport. Spells that require reflex saves and hinder movement.

Creatures with Spell Resistance at lower levels.

Variants
Alternately, you could could switch out Entropic Warding with Darkness and cast it on yourself. Devil's Sight would allow you to see through it, and everyone around you would have a 20% miss chance against you.
