...Is there a way for my to track down which query plans are generating the increased number of hash joins, or some how see what exactly is creating these work files?...
You sure can check the plans in cache, and search the XML for "Hash Match" occuring.
This might give you a start
SELECT * FROM sys.dm_exec_cached_plans AS dm_exec_cached_plans
CROSS APPLY sys.dm_exec_sql_text(dm_exec_cached_plans.plan_handle) dm_exec_sql_text
CROSS APPLY sys.dm_exec_query_plan(dm_exec_cached_plans.plan_handle) dm_exec_query_plan
you can then use the nodes function to serach the XML from the plan
