    @Command='EXEC CheckNew.dbo.FailureMail_prc @LogId='+cast ( @LogId as nvarchar(100))

    or

    @Command='EXEC CheckNew.dbo.FailureMail_prc '+cast ( @LogId as nvarchar(100))

    Also ,

    put a Value in @LogId before you exec the string query.

    edit

    declare @tmp nvarchar(max)
set @tmp='EXEC CheckNew.dbo.FailureMail_prc '+cast (@LogId as nvarchar(100))



 exec [DB].[dbo].SendMail_prc
        @Command=@tmp
        ,@MailPriority=1
        ,@MailRecipients='abc@xyz.com'
        ,@Subject='Alert-Failure'
