The PHB states:
There is no such thing as an off-hand attack for a monk striking unarmed.
and
When using flurry of blows, a monk may attack only with unarmed strikes or with special monk weapons (kama, nunchaku, quarterstaff, sai, shuriken, and siangham).
The FAQ states:
Can a monk fight with two weapons? Can she combine
a two-weapon attack with a flurry of blows? What are her
penalties on attack rolls?
A monk can fight with two weapons just like any other
character, but she must accept the normal penalties on her
attack rolls to do so. She can use an unarmed strike as an offhand
weapon. She can even combine two-weapon fighting with
a flurry of blows to gain an extra attack with her off hand (but
remember that she can use only unarmed strikes or special
monk weapons as part of the flurry). The penalties for two weapon
fighting stack with the penalties for flurry of blows.
and
The monk can’t use his natural weapon attacks as part of a
flurry of blows, but he can make natural weapon attacks in
addition to his flurry.

Monks and Natural Weapons
As we saw in Part Two, a creature with natural weapons can use them for secondary attacks when using the full attack action. A monk character with natural weaponry has the same option.
For example, an 8th-level lizardfolk monk with a Strength score of 17 has a base attack bonus of +7 (+1 for its 2 humanoid Hit Dice and +6 for its monk levels). The character has three natural weapons: two claws (1d4) and one bite (1d4). For this example, we'll assume the character also has the Multiattack feat.
With the full attack action, our example monk can make two unarmed attacks thanks to its +7 base attack bonus. After adding in the +3 bonus from the monk's Strength score of 17, our example character's unarmed attacks have the following attack bonuses: +10/+5. Thanks to the monk's class level and Strength score, damage for the unarmed strikes is 1d10+3.
The example monk also can attack with its claws and bite as secondary natural attacks at a -2 penalty (thanks to the character's Multiattack feat). Each natural weapon uses the character's +7 base attack bonus and +3 Strength modifier, except that the Strength bonus on damage is halved because these are secondary attacks: 2 claws +8 (1d4+1) and bite +8 (1d4+1).
As noted last week, there are no two-weapon or off-hand penalties for these attacks.
The example monk cannot use a flurry of blows because a flurry doesn't work with natural weaponry.
and
If a monk is not using her flurry of blows ability, she can claim an extra attack from a second weapon.
