How to identify all stored procedures referring a particular table
SELECT Name
FROM sys.procedures
WHERE OBJECT_DEFINITION(OBJECT_ID) LIKE '%TableNameOrWhatever%'
BTW -- here is a handy resource for this type of question: Querying the SQL Server System Catalog FAQ
The following works on SQL2008 and above. Provides a list of both stored procedures and functions.
select distinct [Table Name] = o.Name, [Found In] = sp.Name, sp.type_desc
from sys.objects o inner join sys.sql_expression_dependencies sd on o.object_id = sd.referenced_id
inner join sys.objects sp on sd.referencing_id = sp.object_id
and sp.type in ('P', 'FN')
where o.name = 'YourTableName'
order by sp.Name
