So I just had a game that we've all been playing for about 2 years now, and I'm 10 levels druid, having shaping focus so level 14 when it comes to wildshape. I went into huge Earth elemental form, and got strong jaw cast on myself.. that's when we all looked at the chart and found 2d10 turns into 4d8, but couldn't find progression after that.
I haven't used wildshape with my unarmed strike yet till now, when one player told me, "Hey you know you can use unarmed strikes while in wildshape right?" So I've been primarily dealing with just Strong jaw for now.
2d10--> 4d8 ---> ?? ----> ??
PaperAngel, out of curiousity, what are your non-druid levels?
The best answer is to look at the feat Improved Natural Attack (bestiary p315). It gives the most clear damage dice progression in the game.
According to the Improved Natural Attack progression 1d10 turns into 3d8 if you are 'two sizes larger'. So: 2d10 turns into 6d8. Enjoy. :)
You can look at it alternately by checking the table on CRB p145...2d10->4d8. Then jump to the Improved Natural Attack progression where 4d8->6d8. Which is the same answer.
Regarding your Unarmed Strike, there is really not much reason to use Unarmed Strike while in Wildshape. Stick to the superior natural weapons.

Well that's one progression higher, and it's 8 levels druid, 10 levels monk, and 2 levels fighter. I'm using improved vital strike with the unarmed monk damage, with dragon style to improve it a bit.
Feats that support it:
Shaping Focus
Monastic Legacy
Edit: Improved not greater
Ahhh ok.
So your options are (BAB and base damage dice only):
Flurry of Blows: +16/16/11/11 for 2d6 (4d6 if you are Huge)
OR
Huge Earth Elemental slam: +15/+15 for 2d10 (6d8 with Strong Jaw)
Improved Vital Strike would be best used with the Strong Jaw Huge Earth elemental damage.
You could consider grabbing Feral Combat Training and then you can use Flurry of Blows and Dragon Style with the better Huge Earth Elemental damage.
