Use SQL Profiler with appropriate events like SP: StmtCompleted ,
T-SQL : StmtCompleted.

Also SQL server 2005 DMVs might help it.

Here is the SQL which will give you the Top 50 CPU consumers.... (This will work only in SQL 2005).

select top 50
qs.total_worker_time / execution_count as avg_worker_time,
substring(st.text, (qs.statement_start_offset/2)+1
, ((case qs.statement_end_offset
when -1 then datalength(st.text)
else qs.statement_end_offset
end - qs.statement_start_offset)/2) + 1) as statement_text,
*
from
sys.dm_exec_query_stats as qs
cross apply sys.dm_exec_sql_text(qs.sql_handle) as st
order by
avg_worker_time desc
