So I have my VRF lite setup in the WLC 9800 oddly enough that includes VLAN(Mobile clients) and Interface twoGi0/0/0 out to the ISP. I cannot however get DHCP. The DHCP server is behind VLAN on the corp network, as we have to have it windows based due to policy, if not I would surely set one up locally. The only issue is that we do not have a SVI on the corp for VLAN...I know the route leak from VRF to global but VLAN is not in the global...but I am unsure of how to set that up... as I do not want communication with anything but DHCP to that VRF.

Try this config:
ip vrf MOBILE-SSID
description MOBILE to ISP
rd 1:1
!
access-list 101 permit ip 207.91.252.28 0.0.0.255 10.74.35.10 0.0.0.255
route-map VRF_TO_GLOBAL permit 10
match ip address 101
set global
!
interface TwoGigabitEthernet0/0/0
description LOCAL INTERNET
no switchport
ip vrf forwarding MOBILE-SSID
ip address 207.91.252.28 255.255.255.248
ip helper-address 10.74.35.10
ip nat outside
negotiation auto
no snmp trap link-status
ip policy route-map VRF_TO_GLOBAL
!

But the VLAN 126 and 35 are an interface vlan? Or they are only layer 2 vlans?
If they are interface vlan then, is different from what I thought
The policy must be applied on the interface vlan that has the VRF on it
ip policy route-map VRF_TO_GLOBAL
The access list must use the source IP of the interfac vlan with VRF and destination the VLAN on the global vrf
access-list 101 permit ip 207.91.252.28 0.0.0.255 10.74.35.10 0.0.0.255

They are layer 2 vlans on the 9800 WLC.

Hello
You have a post open already (here) relating to the same query ( vrf, vlan 126,dhcp) in this that post it was summarized to
@paul.driver wrote
So just to summarise, you have a HSRP vlan that you want isolated from the rest of the network, be able to receive dhcp allocation and append NAT redundancy to froma 9300 series switch?

That would be a correct summarization. VLAN126 is for mobile traffic to be isolated from other VLANs, minus the possible DHCP,
