So the main thing you need to do is disable the incorporeal subtype. Lucky Aaron added easy logic for this. Though I would also make this ability activatable on the In-Play tab so the DM can turn it on/off as needed.

Run this script at First/510:

~ If ability not active get out now!
doneif (field[abilActive].value = 0)

~ Remove the incorporeal subtype
perform hero.assign[NoTypeAbil.stIncorpor]

Then we need to set Str to be same as Cha:
Pre-Attributes/100:

~ If ability not active get out now!
doneif (field[abilActive].value = 0)

~ Set the starting Str modifier to the same as the Cha score
hero.child[aSTR].field[aStartMod].value = hero.child[aCHA].field[aStartMod].value

Now then we have a tag on the "hero" that now tells us if we are incorporeal or not. So lets use that to our advantage.

I assume you set the Incorporeal Touch Attack as an "Other Melee Weapon" on the race. So add a bootstrap condition to it:
First/600

!NoTypeAbil.stIncorpor

Add the above logic to the "xFly" helper also so we lose fly when not incorporeal.

Then add Two Slam Attacks with the following bootstrap condition:
First/600

NoTypeAbil.stIncorpor

So these can be added to the same Racial Special of "Stolen Power". You can now easily add typed bonuses to the character for attack and damage:

      ~ If ability not active get out now!
      doneif (field[abilActive].value = 0)

      hero.child[Attack].field[BonProfane].value += field[abValue].value
      hero.child[Damage].field[BonProfane].value += field[abValue].value

In this example I preset the field abValue to be 2. This way if ever needed its easy to adjust this value up or down using an Adjustment.

I had to write a little of this so if I can I will finish out this module to be added to the GM Pack. Or happy to take other stuff you have done. Attached is an example source of this monster.
