I have a table with a trigger (on update) on it. When the trigger is executed I would like to know the name of the stored procecure which updated the table in question.

This won't always be 100% reliable, and it sometimes will capture the outer procedure call even if that procedure called an inner one. But you can at least get some idea of what the user called that ended them up in the trigger.

ALTER TRIGGER dbo.whatever
ON dbo.something
FOR UPDATE
AS
BEGIN
    ... other trigger logic

    DECLARE @ExecStr varchar(50), @Qry nvarchar(255)

    CREATE TABLE #inputbuffer 
    (
      EventType nvarchar(30), 
      Parameters int, 
      EventInfo nvarchar(255)
    )

    SET @ExecStr = 'DBCC INPUTBUFFER(' + STR(@@SPID) + ')'

    INSERT INTO #inputbuffer 
    EXEC (@ExecStr)

    SET @Qry = (SELECT EventInfo FROM #inputbuffer)

    SELECT @Qry AS 'Query that fired the trigger', 
     SYSTEM_USER as LoginName, 
     USER AS UserName, 
     CURRENT_TIMESTAMP AS CurrentTime

   -- of course you can store this somewhere instead of select
END

You may also want to check out this question, which has an answer relating to using sys.dm_exec_query_stats - you can track back to procedure name using the object id exposed by sys.dm_exec_sql_text, and you can limit to very recent invocations using GETDATE() as a guide for "recent." There is also a lengthy example of using Extended Events to do it.

Or these ones which use CONTEXT_INFO (but this requires changing all of the stored procedures that update the table):
