How do I get Souls?

Question

A lot of the cool new recipes in patch 1.1 I've found out via asking the Guide require some sort of Soul, of which there appear to be numerous different types. For example:

• Soul of Light
• Soul of Night
• Soul of Might
• Soul of Fright

I've played for a couple hours, and I've yet to find a single one of any type of Soul. How do I get them? Do I maybe need a special item to extract them from slain monsters?

Answer 1

Soul of Flight: Wyvern
Soul of Fright: Skeletron Prime, Hardmode Skeletron
Soul of Light: Hallowed enemies (Illuminated Slime, etc)
Soul of Might: Destroyer, Hardmode Eater of Worlds
Soul of Night: Corrupted enemies (Green Jellyfish, Eater of Souls, etc.)
Soul of Sight: The Twins (Spazmatism and Retinazer) Hardmode Eye of Cthulu

Crafting recipes for the mechanical summoning totems are easliy gotten from The Guide by showing him Iron or Copper bars.

It should also be noted that in order for these monsters to appear, one must first defeat the Wall of Flesh.

Answer 2

The souls can be farmed from new mobs after you beat wall of flesh.

So far I have found soul of flight witch is collected from dragons. I found the dragons on my path I made for collecting stars, near the top of the world, where grav has less effect.
