If I remove SOA from the powerdns data, then it recurses fine, however, it no longer answers for data that is in the powerdns records. How do I set up the pdns config file so that it will answer for records that it has in it's data that it is SOA for, and forward these to the recursor server if the data isn't there?
This is exactly the case, and yes, if you remove the SOA record, 
powerdns becomes severely confused. 8-) I refer to the paragraph in Ch 
15 of the power dns manual:

"To make sure that the local authoritative database overrides recursive 
information, PowerDNS first tries to answer a question from its own 
database. If that succeeds, the answer packet is sent back immediately 
without involving the recursor in any way. This means that for questions 
for which there is no answer, PowerDNS will consult the recursor for an 
recursive query, even if PowerDNS is authoritative for a domain! This 
will only cause problems if you 'fake' domains which don't really exist."

What I want to do is have powerdns consult the recursor even of powerdns 
is authoritative for a domain. This is what I can' seem to get to work.
