In SQL Server 2012, 2014:

USE mydb
GO


ALTER ROLE db_datareader ADD MEMBER MYUSER
GO
ALTER ROLE db_datawriter ADD MEMBER MYUSER
GO

In SQL Server 2008:

use mydb
go


exec sp_addrolemember db_datareader, MYUSER
go
exec sp_addrolemember db_datawriter, MYUSER
go

To also assign the ability to execute all Stored Procedures for a Database:

GRANT EXECUTE TO MYUSER;

To assign the ability to execute specific stored procedures:

GRANT EXECUTE ON dbo.sp_mystoredprocedure TO MYUSER;

From SQLServer 2012 more elegant alter role:

use mydb
go


ALTER ROLE db_datareader
ADD MEMBER MYUSER
go
ALTER ROLE db_datawriter
ADD MEMBER MYUSER
go

It will be better to Create a New role, then grant execute, select ... etc permissions to this role and finally assign users to this role.

Create role

CREATE ROLE [db_SomeExecutor]
GO

Grant Permission to this role

GRANT EXECUTE TO db_SomeExecutor
GRANT INSERT  TO db_SomeExecutor

to Add users database>security> > roles > databaseroles>Properties > Add ( bottom right ) you can search AD users and add then

OR 

   EXEC sp_addrolemember 'db_SomeExecutor', 'domainName\UserName'
